As Egypt prepared to release official results from the constitutional referendum, its economy showed increasing signs of distress on Tuesday with worried residents hoarding dollars and fearing that continued political instability will lead to a fast devaluation of the local currency. The Central Bank of Egypt said Tuesday that the U.S. dollar was selling at 6.18 to the Egyptian pound, a spike from the rate of six pounds just two months ago. (AP Photo/Khalil Hamra)
